As part of a project that lasted a year and a half, The Metropolitan Water Reclamation District of Greater Chicago (MWRD) performed structure rehabilitation and pipelining along 175th Street and Ridgeland Avenue in the Chicago suburb of Tinley Park, Illinois. The project’s objective was to update the infrastructure and prevent further deterioration of existing pipes and structures. Located primarily within the boundaries of Cook County in Illinois, the MWRD District had to rehabilitate the Calumet Intercepting Sewer 19F, constructed in the 1960s.
The work involved the reconstruction of certain sections of deteriorated sewer pipe. Instead of digging up and replacing the old line, Insituform Technologies — the company awarded the multi-million dollar contract — inserted a cured-in-place lining inside 14,051 feet of 60-inch sewer pipe. This created a new, smooth-surfaced, long-lasting pipe within the old pipe.
